Round, square, flat, or beveled flexible screws in any length from 3 to 12 meters are offered to convey virtually any free- and non-free-flowing bulk material including products that pack, cake, seize, smear or break apart.
The only moving part contacting material is the inner screw, which self-centers as it rotates, providing ample space between the screw and tube wall to minimize or eliminate grinding. The lower end of the screw requires no bearing, while the upper end is driven beyond the point of discharge, preventing material contact with bearings or seals.
Fully enclosed, the conveyor tube prevents product and plant contamination, while the gentle rolling action imparted by the screw prevents the separation of blends.
Model 1450 is available with an optional start-stop control panel and a range of flow-promotion devices and is available on a Quick Ship basis in the Americas and in Europe.
